Q:

Hypothetically, what would be the energy (in joules) required to maintain a specific car (described below) at 50 mph on a flat concrete surface for 1 mile. The specifics of the car are as follows: Total weight: 205 lbs
rolling resistance: 0.0025
drag coefficient: 0.14
Frontal Surface area: 13.295 sq ft
It also might make a difference that the car only has three wheels, 2 in front and 1 centered in back. The back wheel is also spherical with a 2 ft diameter. The front wheels are standard size.
If you could include the calculations used, that would be very helpful.
